The non-uniform generation of heat at the friction interface of both disc and drum brakes is undesirable and can degrade the performance of the system. Thermal judder, which is believed to result from localised thermo-elastic instabilities at the interface, is one such problem. The interaction between the friction material and rotor is studied through use of a fully coupled finite element model which takes into account any time dependent change in contact between the two rubbing surfaces. A parametric study is conducted to illustrate how the procedure can be used to investigate the friction pair material properties in order to optimise the system behaviour.
